Drop down value not saving into database

So I have this drop-down that populates from the database depending on the user(it's just an id), the problem is that when I save the form that value is not saved into the forms table its getting NULL on the database and all other values are saving correctly, this was working a while ago but I don't know what happened.

Are you using server-side Blazor or WebAssembly? Can you try to debug what is submitted on Save?

Thank you for your reply but I did find the issue that was causing this.
